The points on this graph represent a relationship between x- and y-values. Which statement about the relationship is true? 4 points in a straight line parallel to y-axis on a line graph. CLEAR CHECK It must be proportional because the points lie in a straight line. It cannot be proportional because the x-values are not whole numbers. It cannot be proportional because a straight line through the points would not go through the origin. It must be proportional because each time y increases by 3, x stays the same.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

15 points! write the slope-intercept form of the equation of the line through the given point with the given slope. use y-y = m(x-x) to solve. through (2,5) slope= undefined
